This follow-up study will determine whether a home nurse visitation program has continued long-term effects on a child's health and development, 27 years later. Specifically, this study will evaluate whether the nurse-visited young adult offspring differ from the comparison group in their economic productivity; rates of child abuse and neglect; criminal behavior; mental health; abuse of substances; use of welfare, foster care, and healthcare in relation to government expenditures; and quality of their partnered relationships. Participants within the nurse-visited program group will be compared with each other to determine whether certain characteristics or factors, such as genetic vulnerabilities, environmental risks, or a history of child abuse, make someone less likely to benefit from a home nurse visitation program.
